1 What is known of Arctic kelps?

1.1 Known

  • Little is known of kelp in the Arctic

1.2 Past

  • Trading in Alaria along Baffin Island coast

1.3 Present

  • There should be other Laminariales sp.

1.4 Other

  • RWS: Other examples?

2 Where are kelp in the Arctic and what drives their distribution?

  • There must be kelp in the Arctic
  • We don’t know what the drivers of their distributions are
  • The Arctic is changing quickly so we should figure this out ASAP

4 Environmental conditions

4.1 Abiotic data

  • NAPA (3-Oceans) model
    • Model outputs supplied by the Bedford Institute of Oceanography (BIO)
    • Based on the NEMO community ocean model
  • Daily surface resolution
  • Five day (pentad) resolution at 75 depth layers
  • Tri-polar grid
    • 10 to 20 km resolution

4.2 Biotic data

  • Bio-ORACLE
    • RWS: Still need to flesh this out Tyberghein et al. (2012) Assis et al. (2018)
